what is the proper length for a Windom wire antenna, to be used from 80 up? Is a 4:1 balun required and where can they be purchased inexpensively?

First, let's clarify. A true window is kind of like a top loaded vertical with the top hat fed off center. I think you are asking about an OCF antenna that everybody is now calling a Windom?
No matter, my 80 meter OCF antenna is 135.5 feet long. I feed it 44.5' in from one end. So one leg is 44.5 feet long and the other leg is 90 feet long. You may want to read the great article in June of 08 QST where the guy makes and uses a 2.8:1 transformer with a current balun. That's what I did and I got much better results.
If you make an OCF antenna and use a 4:1 voltage balun like everybody else does, you better back it with a 1:1 current balun.
